President Obama's spokesman offered no explanation for his boss's decision to skip the memorial marking the 150th anniversary of Abraham Lincoln's Gettysburg Address.

"I don't have any scheduling updates to provide to you," White House press secretary Jay Carney.

Obama came under criticism for the decision to skip the event from local media last month.

"For a president who has so demonstrably associated himself with Lincoln -- the heir of Lincoln's policies who announced his candidacy from the steps of the Old State Capitol in Springfield and used the Lincoln Bible (twice) at his inauguration -- this is nothing less than a profile in cowardice," Donald Gilliland wrote at

Obama did participate in a PBS promotion of Ken Burns' documentary on the Gettysburg Address.

"With regards to the president, beyond what you just described, I don't have anything more for you," Carney said in reference to the PBS work.
